Article 84 builds your EOSB from two accrual rates stacked in sequence: half a month's wage for each of your first 5 years, then a full month's wage for every year after that. The two rates don't blend retroactively, your first 5 years always accrue at the half-month rate, and only years beyond that pick up the doubled rate. Unlike the UAE's gratuity, there's no 2-year cap here, the full-month rate keeps accruing indefinitely, which is why long-tenured employees in Saudi Arabia can end up with meaningfully larger end-of-service payouts than an equivalent UAE tenure.
How you leave changes what you actually get, but only if you resign. Employer-initiated termination, redundancy, and a handful of other qualifying exits all pay the full Article 84 award regardless of tenure. Resignation is where Article 85's tiers kick in: nothing under 2 years, one-third from 2 to under 5 years, two-thirds from 5 to under 10 years, and the full award from 10 years onward. These are hard steps, not a sliding scale, so crossing a tier boundary by even a day matters more than crossing it by a year within the same tier.
EOSB and GOSI run on entirely separate tracks. GOSI is an ongoing payroll deduction that only applies to Saudi nationals, funding pension and unemployment insurance. EOSB applies identically to Saudi nationals and expatriates alike, it's a Labor Law entitlement based purely on wage and tenure, paid by the employer directly at exit, with nothing routed through GOSI at all.
